我最近购买了一个用过的开发板来开始工作。我设法用Mendel 5(Eagle(启用的SSH进行了闪存，并按照入门上的说明进行了操作，直到我尝试了演示。
我根本无法让它工作！
如果我运行edgetpu_demo--流
我得到：
shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
Press 'q' to quit.
Press 'n' to switch between models.

这似乎更接近，但也不知道如何解决。我已经尽可能多地搜索了(向用户添加了plugdev，确保所有东西都安装正确(
有什么想法吗？可以肯定的是，如果这不起作用，有些东西就相当坏了。
感谢您的联系，这绝对不是一个好兆头。
